Quick question though... What is the difference between the GP4000 and GP4000 S? Is it just TPI count, thickness and price?

So far, the GP4000 is in the lead simply by the fact that it has been most recommended thus far. Keep the responses coming!!!

Thanks!

I think the GP 4000S where the first Conti tires to use the "Black Chili Compound" and are only made in Black, therefore the S for schwarz in German... And yeah, in addition to the other stuff you mentioned.

You'll be back on the GP4000's as soon as you wear out the force/attack....which will be quite quickly!!! No diffe between them except the force/attack wear out in front of your eyes. Complete waste of money IMO.

The Michelin Krylion Carbons seem to be a very popular choice amongst many. But I owned one set and got rid of them after about 1000 miles. The worst clincher tyre that I have ever used period. And I have used quite a few. They may have good puncture resistance. But that is the best I can say about them. Getting them on the rim is also a major hassle. They are not the tire that they are hyped up to be. Would never buy again.

Also while on the subject of the continental GP4000S. Great tyre that they are. And Iv'e owned several sets. On one tyre that was being used on the rear, after approximately 1500 miles, the side wall developed a cut of about 5mm, leaving the inner tube protruding through the side wall. Needless to say but I will any how. The tire was binned immediately. So the GP4000S are not without flaws. And yes before any one asks. The tire was always kept at the recommended pressure and checked prior to every ride.

Veloflex/Vredestein is my favorite for racing, but I've found the Veloflex to be very difficult to get on and of of rims which I wouldn't want to deal with on the side of the road. The other thing is that those tubes are nearly impossible to get...at least for the common consumer.
